There are no recommendations that are widely agreed upon for how to follow patients once they have completed therapy for lung cancer. The options are to use chest x-rays, CT scans, or CT-PET scans. Most physicians treating lung cancers will follow patients more closely (every 3-6 months) for the first 2 years after treatment, when they are at the highest risk for recurrence, but patients will often continue to be followed with life-long annual surveillance thereafter.
